  • Rezaie Heris, Hadi (2023-04-17)
    In this dissertation, we calculate the electronic charge and heat transport generated by a temperature gradient and a chemical potential bias in tubular semiconductor nanowires, in the presence of a magnetic field. We use the Landauer-Büttiker approach ...
  • Gudmundsson, Vidar; Manolescu, Andrei; Nemnes, George Alexandru; Sitek, Anna; Erlingsson, Sigurður Ingi; Rosdahl, Tómas (American Physical Society (APS), 2016-05-31)
    We analyze theoretically electronic transport through a core-shell nanowire in the presence of a transversal magnetic field. We calculate the conductance for a variable coupling between the nanowire and the attached leads and show how the snaking ...
  • Khosa, Rabia Yasmin (2017)
    Silicon is a semiconductor material used in most power devices and the Si metal-oxide-semiconductor field effect transistor (MOSFET) is the key switching device for high power applications. Recently silicon carbide (SiC) MOSFETs have emerged on the ...
  • Urbaneja Torres, Miguel (2020-02-25)
    In this work, fundamental electronic and optical properties of semiconductor prismatic nanowires, which are a direct consequence of their geometry, are numerically studied. The quantum states of electrons confined in polygonal shells, which describe ...
  • Kibis, O. V.; Kyriienko, O.; Shelykh, Ivan (IOP Publishing, 2020-03-23)
    It is shown theoretically that the strong coupling of electrons in a bulk gapless semiconductor (HgTe) to a circularly polarized high-frequency electromagnetic field induces topological states on the surface of the semiconductor. Their branches lie ...
  • Emmanuele, R. P. A.; Sich, M.; Kyriienko, O.; Shahnazaryan, V.; Withers, F.; Catanzaro, A.; Walker, P. M.; Benimetskiy, F. A.; Skolnick, M. S.; Tartakovskii, A. I.; Shelykh, Ivan; Krizhanovskiǐ, Dmitry N. (Springer Science and Business Media LLC, 2020-07-17)
    Highly nonlinear optical materials with strong effective photon-photon interactions are required for ultrafast and quantum optical signal processing circuitry. Here we report strong Kerr-like nonlinearities by employing efficient optical transitions ...
  • Sultan, Muhammad Taha (2019-11-27)
    Growth of self-assembled quantum dots is of great interest due to their potential quantum confinement effect and numerous applications in optoelectronics and nano-sized structures. Semiconducting Si, Ge and SiGe nanocrystals (NCs), embedded in a ...
  • Yagafarov, Timur; Sannikov, Denis; Zasedatelev, Anton; Georgiou, Kyriacos; Baranikov, Anton; Kyriienko, Oleksandr; Shelykh, Ivan; Gai, Lizhi; Shen, Zhen; Lidzey, David; Lagoudakis, Pavlos (Springer Science and Business Media LLC, 2020-01-22)
    Bose-Einstein condensates of exciton-polaritons in inorganic semiconductor microcavities are known to possess strong interparticle interactions attributed to their excitonic component. The interactions play a crucial role in the nonlinear dynamics of ...
  • Kravtsov, Vasily; Khestanova, Ekaterina; Benimetskiy, Fedor A.; Ivanova, Tatiana; Samusev, Anton K.; Sinev, Ivan S.; Pidgayko, Dmitry; Mozharov, Alexey M.; Mukhin, Ivan S.; Lozhkin, Maksim S.; Kapitonov, Yuri V.; Brichkin, Andrey S.; Kulakovskii, Vladimir D.; Shelykh, Ivan; Tartakovskii, Alexander I.; Walker, Paul M.; Skolnick, Maurice S.; Krizhanovskii, Dmitry N.; Iorsh, Ivan V. (Springer Science and Business Media LLC, 2020-04-09)
    Optical bound states in the continuum (BICs) provide a way to engineer very narrow resonances in photonic crystals. The extended interaction time in these systems is particularly promising for the enhancement of nonlinear optical processes and the ...
  • Capps, Jeremy; Marinescu, D. C.; Manolescu, Andrei (American Physical Society (APS), 2016-02-09)
    We demonstrate that a spin-dependent Seebeck effect can be detected in quantum wells with zinc-blend structure with equal Rashba-Dresselhaus spin-orbit couplings. This theory is based on the establishment of an itinerant antiferromagnetic state, a low ...
